NCF – Extended list of Neutral creatures.

Guards and Templars are perfect names. But I'm not sure about Praetorians. They were essentially improved legionaries or the emperor's personal bodyguards. Therefore, their connection to the order seems questionable.

Although I can't think of more suitable names right now.

I took the name Praetorians from Might & Magic X - it seems that the elite guards were called that until they were translated into Russian...

As for the order, I'll say this - if it wasn't in the sixth game, then after the change of regime, it could have been an order based on old codes and oaths.
